Susceptibility of the carob moth,Ectomyelois ceratoniae, toBacillus thuringiensis

  • I. Harpaz
  • M. Wysoki


A 1% concentration ofBacillus thuringiensis wettable power (containing 16,000 IU/mg), applied at a rate of 48,000 IU/cm2, killed 95% of 4th-instar larvae of the carob moth,Ectomyelois ceratoniae (Zeller) (Lepidoptera: Pyralidae), after 66 h and 100% after 85 h of exposure in laboratory tests. The mortality caused by a 0.5% concentration (24,000 IU/cm2) was significantly lower and presumably inadequate for practical application against this pest.
